Max Rope Diameter: 13.0 mm
STerling's Single Prusik-Minding Pulleys and Double Prusik-Minding Pulleys are specifically designed to keep the progress capture prusik from getting sucked up into the pulley system and allowing a rescuer to tend to another task. Both single and double versions are compatible with ropes up to 13 mm. All Sterling pulleys are constructed from high-strength aluminum side plates and feature a sealed ball bearing sheave that helps keep out dirt and grit.
